Dimensionally our #140-1 roller chain conforms to all ANSI Standards, but when it comes to the metallurgy, manufacturing process, and performance we like to exceed the "industry standard" while remaining at an economical price point of just $144.99 per 10-foot box, this includes an additional connecting link. We work with manufacturers who have expanded past the basic roller-chain process since it was initially invented in 1880.
140 Roller Chain Features
- Heat-treated and shot-peened side plates, rollers, bushings, and pins - This not only increases the fatigue strength of the chain, but it dramatically improves the overall working life and dependability of the chain.
- Factory pre-loaded - This dramatically reduces initial chain stretching that is common with other chains in the same price level, thus improving sprocket life and performance.
- Pre-lubricated from the factory- All of our roller chains are supplied with proven high-quality lubrication that is applied at the factory level. We also provide additional roller chain lubricants to keep your chain running at its optimal performance and longest possible life.
- Solid Rollers - The implementation of a solid roller has proven to increase the working life and performance of a chain. This is due to the simple fact that the roller is the primary wear part that comes in direct contact with the sprocket tooth. A split roller will deform and cause a hyper-wear effect past a certain point.
